A nurse is reviewing the laboratory values of four clients. Which of the following values indicates to the nurse that a client has iron-deficiency anemia?

A client whose hematocrit is 42%

A client whose hemoglobin is 15 g/dL

A client whose ferritin level is 8 ng/mL

A client whose RBC count is 5.2 million/mm3

Answer and Explanation

The Correct Answer is C

Iron-deficiency anemia is characterized by a deficiency of iron, which is necessary for the production of hemoglobin in red blood cells. Ferritin is a protein that stores iron in the body, and a low ferritin level is an indicator of depleted iron stores.

Ferritin: The normal range for ferritin varies depending on the laboratory, but typically it is around 12 to 300 ng/mL for females and 12 to 500 ng/mL for males. A client with a ferritin level of 8 ng/mL has a significantly low level, suggesting iron-deficiency anemia due to depleted iron stores.

Hematocrit: The normal range for hematocrit is around 36% to 46% for females and 38% to 50% for males. A client with a hematocrit of 42% falls within the normal range and does not suggest iron-deficiency anemia.

Hemoglobin: The normal range for hemoglobin is approximately 12 to 16 g/dL for females and

13.5 to 17.5 g/dL for males. A client with a hemoglobin level of 15 g/dL is within the normal range and does not indicate iron-deficiency anemia.

RBC count: The normal range for red blood cell (RBC) count is roughly 4.2 to 5.4 million/mm3 for females and 4.7 to 6.1 million/mm3 for males. A client with an RBC count of 5.2 million/mm3 falls within the normal range and does not indicate iron-deficiency anemia.

Correct Answer is A

Explanation

Canola oil: Canola oil is a healthier option when it comes to cooking oils. It is low in saturated fat and high in monounsaturated fat, which is beneficial for heart health. Monounsaturated fats can help lower LDL (bad) cholesterol levels when used in place of saturated fats. Canola oil is a versatile oil that can be used for various cooking methods, including sautéing, baking, and grilling.

Palm oil: Palm oil is high in saturated fat and should be limited or avoided when trying to decrease saturated fats in the diet. High intake of saturated fats can raise LDL cholesterol levels and increase the risk of heart disease.

Peanut oil: Peanut oil is another good option for cooking. It is low in saturated fat and contains a good amount of monounsaturated fat. Using peanut oil in moderation can be a healthier choice compared to oils high in saturated fat.

Stick margarine: Stick margarine is not recommended when trying to decrease saturated fats in the diet. Most stick margarines are high in trans fats, which are even more detrimental to heart health than saturated fats. Trans fats can increase LDL cholesterol levels and decrease HDL (good) cholesterol levels, thereby increasing the risk of heart disease.

A. Omeprazole B. Zolmitriptan C. Prednisone D. Verapamil

Correct Answer is C

Explanation

Prednisone is a corticosteroid medication that is commonly prescribed for various conditions due to its anti-inflammatory and immunosuppressive effects. However, corticosteroids can impair wound healing by reducing the body's inflammatory response, delaying collagen synthesis, and weakening the tensile strength of the wound. This increases the risk of wound dehiscence, which is the separation or opening of surgical incisions.

Omeprazole is a proton pump inhibitor used to reduce stomach acid production and prevent gastric ulcers but does not directly affect wound healing or increase the risk of wound dehiscence.

Zolmitriptan is a medication used for the acute treatment of migraines and does not directly affect wound healing or increase the risk of wound dehiscence.

Verapamil is a calcium channel blocker used to treat high blood pressure and certain heart conditions. It does not directly affect wound healing or increase the risk of wound dehiscence.
